Theresa, I Google Imaged “frogs’ nostrils” and there are a few helpful diagrams there. I believe I can discern them on this little fellow, although they are tiny, just to either side of his nose-point.
While we are at it, might I suggest that The Frogs’ Nostrils might be a good name for a band? Or perhaps a new superlative, along the lines of the cat’s pajamas? “Why, that bowl of pudding I just had was really the frog’s nostrils!”
